Purple bits :)

[DomRC]

Received my new Cat SX S1 Composite a few days ago and am in the process of installing the radio gear etc and getting the wiring neat and tidy.

The kit came with a bag of bits to do the finishing touches - servo horns, ballstud for servo, bits to align the battery (which I don't need as I got the very tidy nortech battery retainer)...

BUT there are a couple of parts in the bag that I can't work out what they are for - the first is a pair of round purple alloy things and the second is a pair of short metal rods (like the rods that fit outside losi rear hubs to drive the wheels)

Can anyone enlighten me please?

Car looks awesome - can't wait to get it running
